2024 Sound Information
A heads up for all running NWOR events. As normal in the region, we are following the National Plan for event operation.
In this case we are following the new sound procedures.
Sound measurement readings will now be made using dBc weighting (was dBa).
If a sound reading is over 100 dBc, the competitor will be notified as soon as reasonably possible. No action is needed from the competitor.
If a sound reading is over 108 dBc, the competitor will be notified they need to made a correction/adjustment to their exhaust to try and reduce it below 108 dBc.
Next year (2025) the SCCA sound commitee is proposing a limit of 105 dBc.
